If you like fast novels, I would recommend "Please Don't Be Dark". Although it doesn't completely meet your requirements, this novel is very interesting. The male lead is a big shot who massacred the Hall of Heavenly Lords, but the female lead mistook him for a little white fish that traveled through the book. In every world, the female protagonist would help the male protagonist overcome his original dark fate, challenging herself time and time again to save the male protagonist. This novel made people feel the interaction and emotional changes between the female protagonist and the male protagonist again and again, making it difficult for people to extricate themselves. I hope you like this fairy's recommendation. Muah ~😗
